International cable and fuse sizes—208 Vac to 240 Vac Ratings
Notes:
- Line and motor cable size is selected according to IEC 60364-5-52:2009 Table B.52.4 for copper
conductor with PVC insulation with a wiring condition of ambient temperature 30 °C in air and an
installation method of “B2” (cables in conduit and cable trunking systems). For other wiring conditions,
please refer to the standard of IEC 60364-5-52:2009 for suitable cable sizes.
- Earthing conductor size is determined by the cross-sectional area of phase conductors according to
IEC/EN 61800-5-1:2007 Table 5. So, if phase conductor size is changed, earthing conductor size should
also be changed accordingly.
- If power cubes or bypass are used, a Class gG/gL fuse is recommended.
